Unless, of course, the secondary has been told (via /etc/hosts, /etc/mail/local-host-names, whatever) that your-domain.com is delivered on the local machine... Of course, it probably won't do any harm either, and could protect you from DNS poisoning. Until some time down the track when you change your primary mail server and can't work out why occasionally email gets sent to the old primary (if it's still around) or gets bounced (if it's not). I'm not saying don't do this, just that it probably deserves to be documented somewhere (possibly as a comment in the DNS zone file around the point where the MX records are defined).
